CREAM-EXTRAG'IOR.

Specification of Letters Patent.

Patented July 11, 1911.

T 0 all whom it may concern:

Be it known that we, ARTHUR WV. SPAULD- ING and CYRENUs K. BENDER,citizens of the UnitedbStates, the latter residing at Oconomowoc, in thecounty of Waukesha and State of lVisconsin, and the former residing atTacoma, in the county .of Pierce and- State of Washington, have inventedcertain new and useful Improvements in Cream-Extractors, of which thefollowing is a specification.

This invention relates to improvements in devices for extracting creamfrom milk or extracting milk from cream, without disturbing the milk orthe cream, as the case may be.

The improved device may be employed either for extracting milk fromcream or cream from milk without material structural changes, but isdesigned more particularly for extracting the milk from the cream, andhas for one of its objects to simplify and improve the construction andincrease the efficiency and utility of devices of this character,

The improved device is designed more particularly for extracting themilk from beneath the cream in the ordinary service bottles employed bymilkmen when delivering the milk, and for the purpose of illust-rationis shown thus applied, and in the drawings thus employed to illustratethe preferred embodiment of the invention; Figure 1 is a side elevation,partly in section, of the improved device applied; Fig. 2

is an enlarged perspective view of the movable plunger, detached.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The improved device comprises a longer tubular arm 10 and a shortertubular arm 11, with the shorter arm connected to the longer arm a shortdistance below its upper end 12, as shown at 13. By this means thecommunication between the two arms is located below the upper end 12leaving a conshorter arm 11, as shown. Slidably disposed in the longerarm 10 is a plunger 14, of any suitable material, such as corkor thelike, and depending from the lower end of the plunger is a projectingportion 15 having the sides cut away to form passages for the air, ashereafter explained.

Connected to the plunger member 1115 is a pulling member, preferably inthe form of a light chain 16, which is'long enough to extend through thewhole length of the longer member 10 with a portion projecting beyondthe lower open end when the plun ger is inits highest position or nextto the closure 13. The flexible member 16 may be connected in anysuitable manner to the plunger, but will preferably be attached to a rod17 which passes entirely through the plunger and is retained by nuts orother fastening devices at the ends.

With a devicethus constructed, the operation is as follows: The chain 16is threaded through the longer arm 10 from the upper end 12 and theplunger 14E15 forced into the member 10 with the reduced portion 15opposite the opening in the shorter member 11. The plug 12 is theninserted and the projecting portion of the chain 16 permitted to runinto the lower end of the member 10 so that the finger or thumb of theoperator may be placed over the lower end of the member 10 to shut 01fthe air. The shorter arm 11 is then passed slowly downward through thecream, indicated at 19, in the bottle 18 and into the milk portion,indicated at 20, care being taken not to disturb the cream. The fingeris then removed from the open lower end of the longer arm 10 allowingthe, air to escape and permit the liquid 20 to rise into the tube 11.The

operator then draws the chain 16 downfrom the member 16, this action ofthe the closure 12 is removed to admit air and stop the flow.

If it is desired to remove the cream from the milk the operation is thesame except that the lower end of the shorter arm 11 is inserted intothe receptacle 18 only far enough to locate the lower end of the member11 just above the division line between the cream 19 and the milk 20,and operating the device in the same manner, care being taken to keepthe lower open end of the arm 11 entirely within the cream portion ofthe contents of the receptacle until the cream is all removed.

If it is desired to employ the improved device for removing cream only aspecial size of the implement may be constructed with the armsshorterbut the construction will be substantially the same, and thismodification would not be a departure from the spirit of the invention,and would not require any structural changes.

The improved device is simple in construction, can be inexpensivelymanufactured of any suitable material and of any suitable size. All ofthe parts being detachable the implement can readily be cleansed andscalded, or otherwise treated to maintain it in sanitary condition.

Having thus described the invention, what is claimed as new is:

A cream extractor including a longer tubular arm of a uniform borethroughout and open at both ends, a shorter tubular arm leading from thelonger arm and spaced from its upper end, a plunger operating in thelonger arm and including an upper portion completely filling the longertube and a lower portion with longitudinal recesses providing airpassages, said upper portion being movable into position above theopening into the shorter arm, a detachable closure for the upper end ofthe longer arm, a flexible member connected to said plunger andextending through the longer tubular arm and adapted to' move theplunger through the same.

In testimony whereof, we aflix our signatures in presence of twowitnesses.
